How To Increase Bass In Car Without Subwoofer

It is a shared desire among individuals to have a commendable level of treble and bass in their automobile’s audio system to amplify the pleasure of music. 

However, alternatives can increase bass response if you cannot install a large subwoofer in your car. Notably, a massive subwoofer placed in the trunk will outperform these alternatives by a significant margin.

Nevertheless, opting for these alternatives offers benefits such as reduced weight on the car, resulting in slightly enhanced performance, and no space in the trunk, which can be utilized for other purposes such as storing groceries or other items. 

If trunk space is a top priority, consider using under-seat mount subwoofers, compact units that fit under the seats and come with built-in amplifiers. Pioneer offers an enclosure subwoofer that directly fits in the compartment where your spare tire is stored, giving it a factory look from the outside. 

If you are still not inclined towards installing a subwoofer in your car but want more bass, our tech team recommends exploring these viable alternatives.

Understanding Bass Frequencies:

Before we dive into how to increase the bass in your car, it’s essential to understand what bass frequencies are. Bass frequencies are the low-pitched sounds that you hear in music. They are usually between 20 Hz and 200 Hz. These frequencies are crucial because they provide the foundation for most music genres.

(Adjusting EQ Settings)

The audio equalization (EQ) settings in your automobile’s audio system can profoundly impact the low-frequency audio output. To expound, EQ refers to the electronic processing of audio signals that allows one to modulate the amplitude of different audio frequencies. Adjusting the EQ settings can significantly amplify the low-frequency audio response of your car’s audio system.

Lower the Treble:

To increase the bass, you should lower the treble. Treble frequencies are higher-pitched sounds that can drown out the bass frequencies. Lowering the treble can create more space for the bass to come through.

Boost the Bass:

To amplify the depth of the low-frequency sounds in your auditory experience, there exists an alternative option: heightening the amplitude of the bass frequencies. Generally, most vehicular audio systems contain a designated configuration to adjust the bass.

Thus, you may augment this feature to accentuate the bass within the music you are listening to. However, be vigilant not to indulge in excess bass intensity, as a superfluity of it can potentially lead to distortion and wreck the integrity of your speakers.

(Positioning Speakers)

The placement of your car’s speakers can also affect the bass output. The closer the speakers are to you, the more bass you hear. To get the best bass response, try positioning your speakers in the following ways:

Move Speakers Closer:

Move your speakers closer to your ears. If your car’s audio system has adjustable tweeters, angle them towards your ears to enhance the bass response.

Place Speakers in Corners:

Placing your speakers in the corners of your car can help boost the bass. This is because the corners of your car act as resonant chambers, amplifying the bass frequencies.

(Using Sound-Deadening Materials)

Sound-deadening materials can also help improve the bass response in your car. These materials reduce the vibrations and resonance in your car’s body, resulting in clearer and more accurate bass.

Add Sound Deadening Mats:

You can add sound-deadening mats to your car’s doors, roof, and trunk. These mats can significantly reduce the road noise and vibrations interfering with the bass response.

(Upgrading Your Speakers)

Upgrading your car’s speakers can also improve the bass output. Speakers specifically designed for bass will provide a more accurate and powerful response. However, speaker upgrades can be expensive, so choosing the right speakers for your budget is essential.

Choose Larger Speakers:

Larger speakers are generally better for bass response than smaller speakers. They have larger cones, which can move more air, resulting in more significant bass output.

Choose Speakers with Low Impedance:

Speakers with low impedance can also help improve the bass response. Impedance is the amount of electrical resistance in a speaker. Lower-impedance speakers require less power to produce the same amount of sound, resulting in a more efficient and powerful bass response.

Upgrade the Speakers Adding and Amplifier:

Replacing the stock speakers in your car with a pair of component speakers powered by an external amplifier is recommended. This is because stock speakers are typically made from low-cost materials like paper cones that do not last long and are prone to distortion. 

Additionally, they have weak bass output due to their subpar quality. Car manufacturers allocate their time and resources to other parts of the vehicle, such as the engine and handling, rather than the audio system. Installing 6×9 speakers on the rear parcel shelf is the most effective option for adding bass to your car’s back. 

These speakers have the largest surface area among car speakers, providing ample bass output and high-quality treble.

In conclusion, upgrading your car’s sound system by replacing the stock speakers with high-quality component speakers and installing 6×9 speakers on the rear parcel shelf is a surefire way to enhance the bass in your car without the need for a subwoofer.

While it may seem daunting, the result will be well worth the effort. With a little research and patience, you can achieve a rich, deep bass sound that will take your driving experience to the next level. So go ahead and take the plunge – your ears (and your passengers) will thank you!


Q: Is increasing the bass in my car without a subwoofer possible?

A: Yes, it is possible to enhance the bass in your car without a subwoofer by upgrading your car’s stock speakers with high-quality component speakers and installing 6×9 speakers on the rear parcel shelf.

Q: What are component speakers?

A: Component speakers are a high-end system with separate tweeters, woofers, and crossovers. They are designed to provide better sound quality and enhanced bass response.

Q: What are 6×9 speakers?

A: 6×9 speakers are a type of oval-shaped speaker that provides a larger surface area than other types of car speakers. This allows them to produce more bass and high-quality treble simultaneously.

Q: How do I install component speakers in my car?

A: Installing component speakers in your car can be a bit complicated and may require some technical knowledge. It is recommended to seek professional help for this task.

Q: Can I install 6×9 speakers in any car?

A: While 6×9 speakers can be installed in most cars, it is important to ensure they are compatible with your car’s audio system before making any changes.

Q: Will upgrading my car’s speakers affect my car’s warranty?

A: In most cases, upgrading your car’s speakers will not affect its warranty. However, it is important to consult your car’s manufacturer or dealer to ensure that any modifications you make are within the warranty guidelines.
